MACHINE FOR FOLDING CAR PET-LININGS.

' SPECIFICATION forming part of Letters Patent No. 270,940, dated January 23, 1883.

r 4 Application filed October 22, 1880. (No model.

To all whom it may concern:

Be it known that I, THOMAS H. FARNHAM, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and 5 useful Improvement in Machines for Folding Carpet-Linings, of which the following is a specification.

The nature of my invention consists in combining with a carpet-lining sewing machine,

to or with any machine for performing similar work, a device for forming in the work, as it is delivered, creases alternately reversed, the creases being formed at each half yard or at any other desired interval, the devices for forming one crease consisting of a hollow V-shaped die, which fits on to a wedge shaped die, while the dies which form the alternating crease consist of a hollow V-shaped die, into which a wedge-shaped die is forced, these two sets of dies working alternately, so as to give the required reversed creases at some predetermined definite intervals.

In the drawings, Figures 1 and 2 represent elevations showing a part of the sides of a 2g carpet-lining sewing-machine. Fig. 3 is a plan showing a part of the carpet-lining machine. Fig. 4 is a sectional and perpective view, showing the leading feature of my inven tion.

Let A A A Figs. 1, 2, and 3, represent the sewing mechanism, which is in this case a series of needles and loopers and their operating devices, constructed on the well-known plan of the VVillcox & Gibbs sewing-machine.

B is the fabric operated upon, in this case carpet-lining. The fabric B passes under the sewing mechanism A A A to the drawing feed-rolls D D, the feed-roll D being operated by a ratchet, E, pawl E, eccentric-link 40 E and eccentric F, which is driven from the sewing-mechanism gear, as shown in Fig. 2. As the finished fabric B passes out from the drawing-rolls it goes between the dies HE and K K. (See Figs. 1 and 4.) At a proper time the die H is thrown down onto the fabric,

| and, in combination with the lower die, H,

creases it, as indicated in Fig. 4, so that it may readily fold as it passes out of the machine. The crease made by the'dies H H forms the fold at W, while the crease formed by the dies K K makes the fold b. These dies are operated alternately by the pin at D Fig. 1, which is connected with the lower feed-rolhl), as shown in Fig. 1, by its shaft and the disk D. These feed-rolls D and D are so proportioned that the fabric delivered by one entire revolution is one yard in length. The pin D operates in its passage the swinging lever L, the link L, and the bell-crank lever L which in turn operates, througha link, L the lower die, H. This forms the crease at b, Fig.

4, which in its turn becomes the fold at b, Fig. 1. The die' K of the set K K is operated by the same pin, D Fig. l, which acts, through the swinging lever M, the link M, the bellcrank M and the link M so as to throw the die K upward, which'action will form acrease to correspond with the one shown at b, Fig. 1. These alternate creases in my machine are one- I half a yard apart, so that the two folds of the bundle make a yard. The driving-wheel D of the sewing mechanism is driven by. a belt, and the motion is transmitted to the other parts by the gears A A and A. (See Fig. 2.)

Having thus described my invention, what I desire to secure by Letters Patent is 1. The combination of the creasing-dies H H with the link L bell-crank lever L link L, swiuginglever L, and pin D all operating together substantially as described, and for I the purpose set forth.

2. The combination of the creasing-dies K K with the link M hell-crank lever M link M, swinging lever M, and pin D all operating together substantially as described, aud for the purpose set forth.
